Javier Jorge starts walking towards South. After walking 25 meters he reaches the bus stop and then he goes towards North. After walking 30 metres, he turns towards East and walks another 10 metres. Then he turns towards south and walks 30 metres. How far and in which direction is he from the bus stop?
Explanation:
Let the bus stop be (0, 0). He walks 30m North to (0, 30), turns East for 10m to (10, 30), and turns South for 30m to (10, 0). He is exactly 10m East of the bus stop.
Suddenly she came out of her house and started running towards the north. After 40 m she turns left and runs for 75 m. Then she turned to the right and ran 30 metres, and then turned to the right and ran 75 metres. In which direction was she running at the end?
